PS4 Slim / PS4 Pro WiFi Bluetooth Module J20H091

If your controllers keep disconnecting or the console can't find your Wi-Fi network, the problem may not be the controller or the router. On the PS4 Slim and Pro, Wi-Fi and Bluetooth share one small module on the board, and when it fails, both wireless functions can suffer.

This listing sells the J20H091 Wi-Fi and Bluetooth module for the PS4 Slim (CUH-2015/2115) and PS4 Pro (CUH-7015/7115/7215). According to the listing, it supports 2.4 GHz and 5 GHz Wi-Fi plus Bluetooth 4.0, measures about 2.0 × 2.0 × 0.5 cm and is soldered to the motherboard.

Signs the module may be faulty

• DualShock 4 controllers won't pair or keep dropping.

• The console can't see Wi-Fi networks, or the signal is weak.

• No Bluetooth headset connection.

• Wireless faults after liquid damage.

Tips for the repair

Rule out the controller, router and antenna cables first. The module is soldered on, so you'll need hot air, flux and a steady hand to remove and fit it.

After fitting, test controller pairing, Wi-Fi on both bands and a Bluetooth headset.
